Title: Process for dressing artificial silk yarn
IPC: D06M15/09
Filed: 1928-05-09
Abstract: 317,117. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 9, 1928. Yarns, treating with liquids.-Artificial silk yarn is dressed by treating it with a cellulose di- or poly-fatty acid or an alkali metal salt thereof or with a mixture of the acids or salts obtained by treating alkali cellulose prepared from cellulose or a conversion product thereof in the presence of caustic alkali with at least twice the proportion of a salt of a halogenated fatty acid necessary for the formation of the mono-substituted compound. In an example, cellulose is soaked in caustic alkali lye and after being pressed and finely divided is kneaded to a homogeneous mixture with sodium monochloracetate. On standing, a viscous pasty mass of the sodium salts of cellulose di- and poly-fatty acids is obtained, which on stirring with water first swells up and then forms a colloidal solution. The cellulose di- and poly-fatty acids are obtained in solution in a similar manner to glue. Thus, they are softened in water for some time at about 50‹ C. and worked up into a uniform magma. Water is then added to effect solution. A solution of the acids is obtained from a solution of the salts by acidifying with acetic acid. The solution should be filtered through a cloth before being used. In normal practice for dressing yarns, solutions containing from 1-2 per cent of the cellulose fatty acids are employed. The cellulose di- and poly-fatty acids or their alkali metal salts can be easily dissolved out of the treated materials by means of water, whether they are present alone or in combination with oil emulsions or with soap preparations. The materials are then ready for dyeing without any further preliminary treatment. When the warp for printed goods, which after weaving are not subjected to a wet process, is treated in this manner, the materials produced become more open and voluminous than the materials produced with dressed warp in the customary manner, since the film of cellulose fatty acid is removed mechanically during the weaving and subsequently dry finishing.

Liquor, e.g. a 50% solution of caustic soda, is concentrated in a falling-film evaporator tube 1 surrounded by a heating-jacket 3c defining an annular channel 9 which is not more than 5 millimetres wide between the tube and the jacket, the channel being supplied with liquid heating- medium (e.g. a molten salt) from an annular chamber 8, surrounding a lower section of tube 1, which chamber is of greater radial width than the annular channel 9, and the heating-medium being withdrawn through an upper chamber 5 also of greater radial width than the annular channel. Liquor to be concentrated is introduced through inlet 2a, flows over the slotted upper end of tube 1, and flows down the inside of the tube in the form of a film. Heating-liquid, e.g. at 450‹C., is pumped through pipe 10 into chamber 8 which has a taper-shaped inner wall 7a so that chamber 8 acts as an annular diffusor leading to channel 9. The temperature of the film of liquor may increase from 140‹C. to 400‹C. as it flows down the tube. Tube 1 is provided with means 4 for compensating expansion. A plurality of evaporator tubes, operated in parallel, may be employed. in which case the heating-liquid will be forced through the jackets of all the tubes by a single pump.

Abstract: 313,280. Lees, A., and Lees, H. May 14,1928. Fixed - abutment type; working - fluid supply; driving arrangements for motors; packing drums, vanes, abutments, and the like.- A rotary engine with axially sliding vanes working in undulating channels in the stator end covers or on undulating cam surfaces projecting into channels in the rotor has the undulations formed so as to provide alternate deep and shallow working spaces. In Fig. 4 is shown a diagram of a steam engine or of a gas engine supplied with precompressed mixture; the cam surface touches the rotor R at the point HP<1>, forms a shallow chamber into which the steam or gas enters through a port I<1> at pressure, and a deep chamber EC<1> in which expansion of the steam or of the gases, after ignition, takes place since this chamber is cut off from the inlet I<1> bv the following vane V. Fig. 8 shows a modification suitable for use as a four-stroke internal combustion engine. Gas drawn into a deep chamber SC<1> is compressed in a. shallow chamber CC' and after ignition at I<1> expands in a second deep chamber FC<1>; a second shallow chamber EC<1> serves as a baffle or abutment whereby the gases are exhausted. If the vanes are divided and pressed apart by springs this second shallow chamber may be modified by extending the surface up to the rotor. The slots S, Fig. 20, in which the vanes slide in the rotor R are of a shape to prevent radial pressure, due to centrifugal force, on the stator. A clutch MCM may be incorporated between the rotor R and the driving shaft DS as shown in Fig. 10. A sequence of alternate deep and shallow working chambers may be arranged around the stator. A number of concentric working chambers may be provided for a rotor and a number of rotors may he arranged axially, being separated by suitably channelled and ported partitions. Labyrinth packings may be provided and also spring-pressed packing members at the point of contact of the channel and rotor.

This roller is advantageously utilized, as in the particular apparatus described, in a secondary operation subsequent to a first operation by a roller rotating about an axis parallel with that of the rim which bends the rim over towards the centre of the wheel. The wheel consisting of two sheaves or half-members e permanently joined together by welding and having a circumferential member d incorporated in the rim portion is clamped between rotating plates a, one of which has a plug b entering the central wheel aperture, and the inwardly projecting rims are beaded over in two steps by rollers f, g on a compound slide. The roller f is first advanced in the plane of the wheel so that the curved surfaces f<1> bend the rims inwardly as shown, the roller g being then advanced between the beads and moved laterally first against one and then against the other to bring them to their final form.

Abstract: A water-soluble hormonous substance, applicable in the treatment of cancerous tumour and gynecological disorders, is prepared by extracting umbilical cord tissue, or the eggs of birds, reptiles, or fish, with boiling water and treating the filtered and evaporated extract with organic solvents, such as alcohol, ether, or acetone, to remove impurities.  For example a porcine umbilical cord is tied at each end, washed in water and drained of blood by flowing water through glass tubes inserted in the blood vessels.  The cord is then dried, not above 100 DEG  C., and ground to powder.  Twenty grms. of the product is boiled for about one hour with 500 c.c. of distilled water, filtered, and the filtrate evaporated.  The residue is extracted for five or six days with 100 c.c. of a mixture of equal parts of ether and acetone, filtered, and the filtration residue dissolved in 100 c.c. of water and again filtered.  To the filtrate is added 150 c.c. of pure alcohol which, in twenty-four hours, throws down albuminous substances.  The last purification step may be repeated several times.
